' CAR-END CONSTRUCTION.

Application ld February 4,1925. SerialNo. 6,740.

Railroad freight cars designed and placed in service a decade `or moreago vare failing to meet present day conditions brought about by thelonger trains, heavier locomotives and the elassitication hump yard.This is particularly true of the end constructions which are beingknocked out or `broken by `the shifting of the lading as the end hasbeen weakened by the torsional and weaving movements of the car inservice, which service conditions it was not designed tomeet. This isespecially true of box and other house cars. l

The end constructions Vfail in numerous ways, the. most frequent ofwhich is bythe end or corner` post breaking or becoming detached fromtheir moorings at top or bottom. The end sills decay and failtoperformtheir function of supporting the draft sills from drooping. The endsheathing decays so t-hat it not only fails to hold the grain within thecar but also does not perform its function as a. gusset or bracing toresist the lateral weaving of the car body.

It is expensive to replace an end of a car on account of the cost ofmaterial and labor, as well as the time the car is out ofservice and,therefore, not producing revenue. Investigation shows that `the ends of`an old box car must be replaced or `repaired two or three times a yearon an average. All steel car ends are in general use andare easilyapplied to new equipnient as the `design can be arranged to accommodatethem,butit'is expensive in time and material to apply such` all steelcar ends for repairs, because the old wooden ends walls of thecanmnst beremoved beforethe steel end is applied. rFhe old end is scrapped andwasted.

It is preferable to provide means for reinforcing and strengthening thevulnerable parts of the old end wall of the old car without necessarilyremoving or replacing the old members thereof, eventhough such framemembers are broken.

'it has been proposed toreinforce the end 'one edge) but to'secure it toa separate connecting member so that the corrugated plate can be appliedto Vany width of car by adkjusting the relative position between thecon- `nectmg member and the corrugated plate.

Thus a particular vcorrugated plate canbc used on any one of a series ofcars.

The invention resides in providing means for adjustment of the relativeposition betweena reinforcing plate forthe end wall of a railway car andits attaching member.

Another object of the invention is to provide a reinforced plate whichnot only aids in resisting the thrusts of the shifting loads, but alsoreinforces the old frame members of the end wall to enable. th'emtobetter resist the lateral weaving movements of the superstructure of thecar.

ln the drawings:

Fig. l is anendelevation of a railway box car showing the device appliedthereon.

Fig. 2 is a section `along line 2 2 of Fig. l.

Fig. 3 is an enlarged section on line 3 3 of Fig. l.

Fig. 4 is a side `elevation of Fig.

Fig. 5 is a fragmentary detail'of the end of the plate shown in Figs. 3and 4.

F ig. 6 is a fragmentary detail ofrthecon-i necting' member of Figs. 3'and 4.

The old component parts of the car are shown wherein l is the end sill;2 the end lplate; 3 the corner post l4 the end: post; 5 the end diagonalbraces; lO the side diagonal braces; 1l the side plate; l2 the side silland 13 the end lining.

The reinforced and reinforcing plate 14 is preferably positioned on theoutside of the car end wall and is secured to the end sill l, the cornerpost 3, end post 4 and' diagonal braces 5, as shown in F ig. l, thusretarding the lateral weaving movements ofthe superstructure of the car.This plate 14 is preferably provided with horizontal corrugations l5 orother stiifening means, terminating within its opposite edges, whichreceive the shocks imposed upon the end wall and transmit them to theconnecting members 1G which are. secured to the car. If these connectingmembers are oll angular formation, one leg (17) is secured to the car(by bolt E25) and the other leg (18) is secured to the plate 14 and tothe car also it desired. As stated, it is desirable to have adjustingmeans between the plate and the ronnecting member, therefore, I providehorizontally slotted holes in either the plate or the connecting memberand provide round holes in the other member. Slotted holes may beprovided in both the plate and connecting mena ber but it preterable tohave slotted holes in the plate and round holes in the connectin member.

it is only necessary to have the means of adjustment at one corner oitthe car as one connecting member and one end ot the plate may be rigidlysecured together before the device is assembled on the car.

In applying the device to the car, one connecting' member 1G is rigidlysecured to the plate 1st and the connecting member attached to the car.The bolts 2O (or other securing devices) without their nuts are thenplaced in the slotted holes 19 at the other end of the plate with theirheads towards the car and held in place by pressing the plate 1a againstthe car. lThe other connecting member 16 is then placed in position andthe bolts 2O moved horizontally in the slotted holes 19 until theyregister with and project through the round holes 21 in the connectingmember, then the nuts are applied to the bolts. rlhis arrangementconstitutes means to provide adjustment oit the relation of the plate tothe connecting mem` ber and at the same time to secure these two partstogether.

The saine relation exists between bolts V2O, slotted holes 19 and roundholes 21 as between bolts 22, slotted holes 23 and round holes 24.However, bolt 22 secures the plate and connecting member to the cornerpost, while the bolt 2O only secures these parts together. Either ofthese constructions may be used and come within the scope ot thisv mentof the relation of said provide adjustment ot the relation ot said plateto said angle.

2. In Vcombination with the end wall of a railway car, a metallic platehaving horizontal corrugations formed therein, said plate provided withholes adjacent one edge thereof, a vertically positioned angle with oneleg having holes therein and with the other leg secured to the car, oneset of said holes being slotted and the other set ot said holes beinground, and means detachably engaging said holes to provide adjustplate.to said angle.

3. In combination with the end Wall of a railway car, a metallic platehaving horizontal corrugations formed therein terminating within, theplate, said plate provided with holes adjacent one edge thereof, avertically positioned angle with one leg have ing holes therein and withthe other leg secured to the car, one set of said holes being slottedand the other set of said holes being round, and means detachablyengaging said holes to provide adjustment of the relation of said plateto said angle.

4. In combination with the end wall oit a railway car, a metallic platehaving corrugations formed therein, said plate proA vided with slottedholes adjacent one edge thereof, a member provided with round holessecured to the car, and means detachably engaging said slotted holes andround holes to provide adjustment of the relative posi` tion betweensaid plate and said member.

5. In combination with the end wall ot a railway ear, a metallic platehaving horizontal `eorrugations formed therein, said plate provided withslotted holes adjacent one edge thereof, a member provided with roundholes secured to the car, and means detachably engaging said slottedholes and round holes to provide adjustment of the relative positionbetween said plate and said member.

6. In combination with the end Wall of a railway car, a metallic platehaving hori- Zontal corrugations formed therein terminating Within theplate, said plate provided with slotted holes adjacent one edge thereof,a member provided with round holes secured to the car, and meansdetachably engaging said slotted holes and round holes to provideadjustment of the relative position between said plate and said member.
